If you don't mind the early spring chill, there is a cherry blossom festival in late March-early April. Besides the cherry blossoms, there is the festival atmosphere over the town, with an open-air bazaar and fireworks. Be sure to go to the mobile food stalls -- you can get freshly-baked (as in right before your eyes) little cakes shaped like fish, with adzuki bean filling; or if you are more adventurous, some kind of insect stir-fried and served in a paper bag like popcorn. In the market districts, you will find all sorts of seafood, including live softshell turtles, if you like that sort of thing. Some of the vendors at the bazaar sell fun, colorful underpants! Get a set of go-stop cards, and find a friendly local to show you how to play. Oh, and be sure to stop into the 1000-won store to get yourself a set of stainless steel chopsticks -- the kind Koreans like to use.
